  • A confidence assessment of WCET estimates for software time randomized caches 

    Benedicte Illescas, Pedro; Kosmidis, Leonidas; Quiñones, Eduardo; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Open Access
    Obtaining Worst-Case Execution Time (WCET) estimates is a required step in real-time embedded systems during software verification. Measurement-Based Probabilistic Timing Analysis (MBPTA) aims at obtaining WCET estimates ...
  • Behavior characterization of the shared last-level cache in a chip multiprocessor 

    Benedicte Illescas, Pedro (Universitat Politècnica de Catalunya, 2014-06-27)
    Master thesis (pre-Bologna period)
    Open Access
    [CATALÀ] Aquest projecte consisteix a analitzar diferents aspectes de la jerarquia de memòria i entendre la seva influència al rendiment del sistema. Els aspectes que s'analitzaran són els algorismes de reemplaçament, els ...
  • Design and integration of hierarchical-placement multi-level caches for real-Time systems 

    Benedicte Illescas, Pedro; Hernandez, Carles; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    Enabling timing analysis in the presence of caches has been pursued by the real-Time embedded systems (RTES) community for years due to cache's huge potential to reduce software's worst-case execution time (WCET). However, ...
  • HWP: hardware support to reconcile cache energy, complexity, performance and WCET estimates in multicore real-time systems 

    Benedicte Illescas, Pedro; Hernandez, C.; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier (Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2018)
    Conference report
    Open Access
    High-performance processors have deployed multilevel cache (MLC) systems for decades. In the embedded real-time market, the use of MLC is also on the rise, with processors for future systems in space, railway, avionics and ...
  • Improving time-randomized cache design 

    Benedicte Illescas, Pedro; Hernández Gañán, Carlos; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier (Barcelona Supercomputing Center, 2018-04-24)
    Conference report
    Open Access
    Enabling timing analysis for caches has been pursued by the critical real-time embedded systems (CRTES) community for years due to their potential to reduce worstcase execution times (WCET). Measurement-based protabilistic ...
  • Locality-aware cache random replacement policies 

    Benedicte Illescas, Pedro; Hernandez, Carles; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier (Elsevier, 2019-02)
    Article
    Restricted access - publisher's policy
    Measurement-Based Probabilistic Timing Analysis (MBPTA) facilitates the analysis of complex software running on hardware comprising high-performance features. MBPTA also aims at preventing additional analysis costs for ...
  • Modelling the confidence of timing analysis for time randomised caches 

    Benedicte Illescas, Pedro; Kosmidis, Leonidas; Quiñones, Eduardo; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Open Access
    Timing is a key non-functional property in embedded real-Time systems (ERTS). ERTS increasingly require higher levels of performance that can only be sensibly provided by deploying high-performance hardware, which however ...
  • On the analysis of the timing behaviour of time randomised caches 

    Benedicte Illescas, Pedro (Universitat Politècnica de Catalunya, 2016-07-07)
    Master thesis
    Open Access
    Time Randomised caches (TRc), which can be implemented at hardware level or with software means on conventional deterministic cache designs, have been proposed for real-time systems as key enablers for Probabilistic ...
  • RPR: a random replacement policy with limited pathological replacements 

    Benedicte Illescas, Pedro; Hernández Luz, Carles; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier (Association for Computing Machinery (ACM), 2018)
    Conference report
    Restricted access - publisher's policy
    Measurement-Based Probabilistic Timing Analysis (MBPTA) has consolidated as a technique to estimate probabilistic Worst-Case Execution Times (WCET) for critical software running on processors with high-performance hardware ...
  • Towards limiting the impact of timing anomalies in complex real-time processors 

    Benedicte Illescas, Pedro; Abella Ferrer, Jaume; Mezzetti, Enrico; Cazorla Almeida, Francisco Javier; Hernández Luz, Carles (2019)
    Conference report
    Restricted access - publisher's policy
    Timing verification of embedded critical real-time systems is hindered by complex designs. Timing anomalies, deeply analyzed in static timing analysis, require specific solutions to bound their impact. For the first time, ...
